Dear Lihua,
I’m very glad to have received a letter you sent me      ______________
two weeks ago. I had been thinking about the question you   ______________
asked me. In my opinion, you should come back before     ______________
you finish your studies abroad. For one reason, which you    ______________
are studying is badly needed nowadays in China. That will  ______________
be pretty easy for you to find a good work. In fact, I know a  ______________
few big companies in one city is hoping to hire people      _____________
like you. For other reason, I think it will be more convenient  ______________
for you to look after your parents as they are getting old.     _______________
Therefore, I think it’s a good idea for you to return back.   _______________
Best wishes!
Minghua
